Definitions
- the present invention relates to a sheet material with a closed cellular structure which also includes sound dampening properties and sound attenuation properties.
- the present invention relates to a composition for producing the sheet material that is also environmentally friendly and in addition, the present invention also relates to a process for producing the sheet material with a closed cellular structure.
- Sound dampening (or acoustic attenuation) properties are found in materials with a high sound transmission loss.
- the sound transmission loss of a material is determined by various physical factors.
- WO2015/007113 A1 discloses a method of producing an open-cell structure porous sheet material, made from a composition comprising producing a porous sheet material, made from a composition comprising 5 -25 wt% PVC, 50 - 75 wt% of fillers, 10 - 40 wt% of a dioctyl terephthalate plasticizer, and 0.05 - 2.0 wt% of a porogen.
- US 5,622,662 discloses a sound attenuation composite and a method for making the composite by casting an open cell foam layer onto a polymer barrier layer.
- a sheet material with sound dampening properties is what is termed a loaded vinyl.
- a loaded vinyl Such a material is produced by formulating a composition with a high density which is then combined with vinyl at formulation stage. The resulting product, or sheet material has a high density whilst still maintaining high flexibility and thereby providing good sound dampening properties.
- the present invention seeks to provide a composition for producing sheet material with sound dampening properties which is better suited to various applications within buildings and building assemblies that loaded vinyl.

- the one or more phthalates are selected from the following: dioctyl phthalate (DOP), diisononyl phthalate (DINP), di-2-propyl heptyl phthalate (DPHP), diisodecyl phthalate (DIDP), and non-phthalates such as 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH), dioctyl terephthalate (DOTP), and citrate esters.
- the plasticiser is dioctyl phthalate (DOP).
- the composition includes about 0.1 to about 1.0 weight% of a cellular structure promoting agent. In one form the composition includes about 0.25 weight % of a cellular structure promoting agent
- the one or more surfactants is/are selected from an alkylbenzenesulfonate, an aliphatic amine oxide or an amine oxide.
- the cellular structure promoting agent includes sodium sulphate.
- the cellular structure promoting agent includes one or more of the following: C12 - C13 alcohol EO 2:1 sodium sulfate; lauramidopropylamine oxide and myristamidopropyl amine oxide.
- the cellular structure promoting agent includes at least two of the following: C12 - C13 alcohol EO 2:1 sodium sulphate, lauramidopropylamine oxide and myristamidopropyl amine oxide.
- the cellular structure promoting agent further includes one or more of the following: magnesium sulphate, tetrasodium EDTA or free oil.
- the present invention provides a process for producing a sheet material with a cellular structure the process including the steps of:
- the first mixture is in the form of an emulsion.
- the mixing in step a. ii. is carried out in an emulsifier.
- the mixing in step a. ii. is carried out in the absence of air.
- the composition is formed into a sheet at step b. using a knife coating step.
- the heating at step c. is conducted at a temperature of about 150°C to about 200°C. In a further form the heating at step c. provides sufficient heat to heat the core of the sheet formed from the composition to about 100 °C.
- the present invention provides a sheet material prepared from a composition as herein described
- the closed cell structure includes an average cell diameter size of between about 0.1 and about 1000 micrometres.
- the sheet material has a density of about 0.8 to about 2.0 g/cm 3 . In another form the sheet material has a density of about 1.0 to about 1.4 g/cm 3 .
- PVC refers to polyvinyl chloride or poly(vinyl chloride).
- PVC may be provided as a constituent of the composition as herein described in the form of a PVC paste resin.
- the filler material included as a constituent of the composition as herein described may be chosen from any suitable material that is generally unreactive within the composition.
- the filler material has a density of between about 2.0 to about 5.0 g/cm 3 .
- Calcium carbonate, sand, glass or recycled glass, silica, Ilmenite, and/or barium sulphate are examples of materials that may be selected as filler materials used individually or in combination.
- the term "plasticiser” refers to an additive that when included within the composition as herein described increases the plasticity or fluidity of the composition.
- the plasticiser may be selected from a phthalate or a phthalate ester.
- the plasticiser may be selected from any one or more of the following: dioctyl phthalate (DOP), diisononyl phthalate (DINP), di-2-propyl heptyl phthalate (DPHP), diisodecyl phthalate (DIDP), and non-phthalates such as 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH), dioctyl terephthalate (DOTP), and citrate esters.
- DOP dioctyl phthalate
- DINP diisononyl phthalate
- DPHP di-2-propyl heptyl phthalate
- DIDP diisodecyl phthalate
- non-phthalates
- the cellular structure promoting agent may selected from a compound that reacts to produce a gas when included in the composition as herein described thereby providing the cellular structure within the resultant sheet material once the composition is cured.
- the cellular structure promoting agent reacts once the composition is undergoing a curing step at an elevated temperature of over 100°C, or in one form at a temperature of about 150°C to about 200°C. According to the invention the cellular structure promoting agent reacts when the core of the sheet formed of the composition reaches approximately 100°C.
- the cellular structure promoting agent includes one or more surfactants selected from an alkylbenzenesulfonate, an aliphatic amine oxide or an amine oxide.
- the cellular structure promoting agent includes one or more of the following: sodium sulphate, magnesium sulphate, tetrasodium EDTA or free oil.
- a cellular structure promoting agent together with the plasticizer and PVC component of the composition provided a composition that when formed into a sheet or other structure and allowed to cured at sufficient heat to heat the core of the sheet formed from the composition to 100 °C by over 100°C and preferably at about 150°C to about 200°C, provided a sheet material with a cellular structure throughout its composition.
- the cellular structure appearing throughout was a closed cell cellular structure that provided the resultant sheet material with significantly increased resilience properties when compared to a material such as commonly known loaded vinyl.
- the cellular structure within the resultant sheet material composed from the composition as herein described provided significant sound dampening or sound attenuating characteristics when compared with a material such as commonly known loaded vinyl.
- the sheet material with a cellular structure once formed has a density of about 0.8 to about 2.0 g/cm 3 .
- the sheet material is very flexible and has a high elastic memory. The combination of the high density and the flexibility provides that the sheet material has excellent sound dampening properties.
- the sheet material with a cellular structure is produced by preparing a composition including PVC, a filler material and a plasticiser and providing a cellular structure within the composition prior to curing to form the sheet material.
- the cellular structure may be provided by incorporating a gas into the composition without a cellular structure promoting agent per se.
- the cellular structure may be provided by incorporating a gas, such as an inert gas into the composition whilst the composition is under pressure. Once the pressure is reduced, the gas incorporated within the composition may expand thereby producing the cellular structure.
- the first mixture (prepared at step a ii) is in the form of an emulsion and the mixing step to produce the first mixture may be carried out in an emulsifier in an environment in the absence of air.
- the emulsifier that may be used for the mixing step may be selected from a "SLOT" type emulsifier which may for example perform the mixing step at an RPM of about 2800.
- step a ii is quite important for the resultant cellular structure of the sheet material produced by the process as it was found that the shear provided in this step meant the cellular structure promoting agent within the composition was activated sufficiently to achieve the desired closed cell structure within the sheet material.
- composition may be formed into a sheet at step b. using a knife coating step. Although it is envisaged there may be other methods of forming a sheet that would be readily apparent to those skilled in the art that may also be used in conjunction with the process as herein described.
- mixing of the PVC into the first mixture (at step a. iii) to form the second mixture occurs at above about 32°C and in certain embodiments up to about 40 °C to achieve the optimum required emulsion mix.
- this temperature requirement was particularly beneficial when sodium sulphate was used as part of the cellular structure promoting agent.
- the shear generated as part of the mixing steps at step a. ii. and step a. iii. is sufficient to heat the mixture up to at least up to 32°C and in certain embodiments up to about 40 °C.
- the filler material is added to the second mixture which may bring the temperature of the resultant composition down from about 40 °C. This may be due to the temperature of the filler material being generally at ambient or room temperature which may be lower than the temperature of the second mixture produced at step a. iii.
- the heating at step c. is conducted at a temperature of about 150°C to about 200°C and this step provides sufficient heat to heat the core of the sheet formed from the composition to about 100°C.
- the mixing step at step a. ii. may take approximately 5 to 20 minutes to complete; the mixing step at step a. iii. may take approximately 40 to 80 minutes to complete; and/or the mixing step at step a. iv. may take approximately 10 to 40 minutes to complete.
- the composition may also be coloured by using any suitable colouring technique to produce sheeting in any colour that may be desired.
- the composition as herein described and/or the process as herein described may be used to produce a sheet material with a cellular structure of various thicknesses.
- the thickness of the sheet material taken from one major planar surface to another major planar surface may be from 1 mm to about 50 mm in thickness and usually in the range of about 1 mm to about 16 mm in thickness for most applications and often in the range of about 4 mm to about 10 mm.
- the sheet material with a cellular structure was found to have increased resilience, low thermal conductivity and increased sound dampening characteristics when compared to commonly used sound attenuation building sheeting material such as loaded vinyl.
- the sheet material with a cellular structure produced in this way was found to be highly suitable for a variety of applications within building assemblies where sound attenuation was desired such as for example as a pipe lagging, an underlay for flooring assemblies as well as for component in wall assemblies.
- the cellular structure of the sheet material produced from the composition and/or the process as herein described unexpectedly had a significant increase in the Sound Transmission Loss (STL) for a given weight by about 2 to 4 dB when compared with other common sound attenuation building products such as loaded vinyl sheeting.
- STL Sound Transmission Loss
- the cellular structure of the sheet material also provides an additional advantage in that it provides significant thermal insulation when used as part of a building construction due to the closed cell cellular structure which provides the thermal rating is very similar to other forms of commercially available insulation.
- the thermal Conductivity for rigid PVC is 0.14-0.28 W/mK and for flexible PVC: 0.14 - 0.17.
- the sheet material with a cellular structure produced from the composition and/or the process as herein described included a specific mass of 20-50 kg/m 3 and a thermal conductivity 0.035 W/mK.
- the sheet material with a cellular structure may be bonded to a construction panel such as for example a plasterboard panel to produce a composite building material.
- a construction panel such as for example a plasterboard panel to produce a composite building material.
- the sheet material with a cellular structure may be sandwiched between two construction panels such as plasterboard to produce a composite building material.
- the sheet material with a cellular structure may be situated between the construction panel in one continuous layer, or alternatively in discrete spaced apart sections. Because of the material properties of the sheet material during the formation stage, it is not required to use an adhesive between the sheet material with a cellular structure and another material such as a construction panel if bonded to the sheet material during the curing step when the sheet material is being produced.
- the construction panel may be composed of any common construction panel material such as for example plaster board, plywood and fibro.
- Such a composite building material may be used in a variety of applications where a construction panel may be used with the added benefit of providing a construction panel with increased sound insulation properties from conventional construction panels.
- the resulting composite building material may be cut to size by first scoring or cutting through the side of they composite material including the sheet material with a cellular structure.
- the composite building material may then be snapped or folded to break through the construction panel layer along the line of the score/cut thereby providing the composite building material in the desired size for a building application.
- the density of the final product can be tuned from 0.8 - 2 SG which equates to a density of about 0.8 to about 2.0 g/cm3.This is achieved by reducing or increasing the cell structure which may be achieved during the mixing step (step a. ii.) wherein if a smaller cell structure is provided then the resultant sheet material has a higher density.
- the acoustic attenuation properties of the sheet material produced by the composition and/or the process described herein were found to be better than the currently available loaded vinyl sheeting by approximately 2-4 dB.
- the sheet material was found to provide a much lighter product by approximately 2 kg/m 2 than the loaded vinyl.
- the sheet material as herein described was found to be particular suitable for applications including under flooring products such as an underlay for ceramic tiles, engineered timber floors or other floor coverings.
- the sheet material was also found to have an increase to its vibration damping effect compared to existing loaded vinyl the sheet material may also be used within wall assemblies where it may be sandwiched between 2 construction boards such as plywood, plasterboard or FC sheeting which was found to increase the overall STL (Sound Transmission Loss) by 2-4 dB.
- 2 construction boards such as plywood, plasterboard or FC sheeting which was found to increase the overall STL (Sound Transmission Loss) by 2-4 dB.
- a sheet material was produced by the following process including the steps of:
- the resulting sheet material was then used as a pipe lagging and a series of acoustic tests were performed to analyse the acoustic attenuation properties of the sheet material.
- Test 1 Pipe Lagged with standard commercially available lagging
- SEL is the sound exposure level
- the cellular structure promoting agent included at step a ii included the following compounds: C12 - C13 alcohol EO 2:1 sodium sulfate; lauramidopropylamine oxide and myristamidopropyl amine oxide, a sheet material with a cellular structure was produced with a thickness of 6mm.
- Table 1 Sample Floor Covering Tested Test ID ID Name Hard Floor Covering 1 Sample Tile + Sheet material Tile loosely laid ontop of 30mm screed 2 Sample Tile + FC sheets + Sheet material Tile laid ontop of 2 layers of 6mm FC 3 Timber + Sheet material 12mm Tongue and groove engineered timber floor
- Instrumentation used to measure noise in this test was a SVAN (Type 1) Sound Analyzer Model 945A Serial No 9418.
- SVAN Type 1 Sound Analyzer Model 945A Serial No 9418.
- One third octave band results were recorded within the instrument for each measurement and these results used to calculate the single number figures and plot the results.
- Impact sound in the source room was generated using a BSWA-TEC tapping machine, Model No TM002, Serial No. 1Z17, manufactured in accordance with the requirements of AS/ISO 140, BS5821, EN 20140, ASTM E492, GB J75-84. Receiver sound was measured in the receiver room directly under the point of impact of the tapping machine.
